C. E. GOULD AUGER Filed July 9, 1923 2 Sheets-Sheet 2 WITNESS:

ATTORNEY Patented July 1, 1924.

COURTIE ELMORE GOULD, 0F CLAY, NEST VIRGINIA.

AUGEB.

Application filed July 9. 1923.

To all whom it may concern:

Be it known that I, COURTIE ELMoRn GOULD, a citizen of the United States, residing at Clay, in the county of Clay and State of West Virginia, have invented new and useful Improvements in Angers, of which the following is a specification.

This invention relates to an auger, the general object of the invention being to provide an adjustable shank for the auger so that the drill can be placed at any angle for permitting a hole to be bored in the floor, the roof or the walls of a mine.

While the invention is mainly designed for use in mines it will of course be understood that it can be used in other situations.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, ref erence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is an elevation of the complete device.

Figure 2 is a similar view but showing the parts in a different position.

Figure 3 is a longitudinal sectional view through the flexible oint.

Figure 4 is a view partly in section showing the connection between the shank and brace.

Figure 5 is a plan view of one of the rings 6.

Figure 6 is a view showing the two members 4c in separated condition.

As shown in these views the brace A is formed with a pair of handles 1 and has a breast yoke 2 swiveled to its top. The shank B is connected with the handle by the coupling 3 and said shank consists of a pair of members 4 which have their ends threaded and the members are connected together by the gimbal joint 5 which consists of a pair of rings 6 into which the prongs of the forks 7 are countersunk so that each member can have rocking movement in the rings when the rings are bolted together. Each carries a nut Serial No. 650,522.

which is provided with a flange 9 to engage the ring part of the joint to limit the rocking movement thereof and to hold the members in alignment with each other when the nuts are screwed tight. The screw threaded end of one of the members engages the coupling 3 and the other member is connected by the coupling 10 with the drill 11. From the foregoing it will be seen that the bit can be rotated by both hands so that a great amount of force can be applied to the bit and by means of the joint in the shank B the bit can be placed at various angles and can be used to bore holes in diiierent positions.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. A device of the class described comprising a brace having a pair of handles, a breast yoke swiveled to the brace, a shank detachably connected with the brace and consisting of two parts, the adjacent ends of the two parts being forked, a pair of rings clamping the forked ends together so that the members can have rocking move ment relative to each other, means for regulating this movement or entirely preventing it and a drill detachably connected with the shank.

2. A device of the class described including a joint between two members consisting of a pair of rings between which the forked ends of the members are pivoted and an adjustable member on each of the two members for engaging the rings to limit the rocking movement or prevent such movement of the joint.

3. A device of the class described comprising a pair of rods having forked ends, a pair of rings between which the prongs of the forks are pivoted and a nut on each rod for engaging a ring to regulate the amount of rocking movement of the rod or to prevent such movement.

ture.
